IMPROVEMENT IN LlFTlNG-PUMPS.

To a/ZZ whom it may concern:

' Beit knownthat we, Frrcrr RAYMOND and AUGUST MILLER, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Pumps; and we do hereby declare that the following is a full and complete description ofthe construction and operation ofthe same, reference being had to the accompanying' drawings, maliing part of this specification, in which- Figure l is a side view, and Fig. 2 is a vcrtcal section.

Like letters refer to like parts.

Our invention relates to such a construetion of a pump that a single turn of the crank will raise as much water as is usually obtained by many revolutions of the crank in the ordinary way of drawing water, thereby requiring less time and labor. rI`he structure is also such that the water is constantly drawn from the bottom of the well, and, being a liftingpump, thewater can be raised any desired distance.

In the accompanying drawings, A represents the barrel or cylinderof the pump. 'Ihis is supported by a framework, B. Ihe lower end of the cylinder is provided with a chamber, C, into which the wateris received before it passes through the valve. The central portion of this chamber, in its conical upper walls, is provided with a valve, D, opening upward into the cavity ofthe cylinder A. The chamber C is provided with openings for the ingress of water from without. Ihe barrel of the cylinder A is about three feet in length and a foot or more in diameter. At the upper part of the barrel proper the tube is contractegl to the diameter of from three to five inches, forming thereby a smallerI tube, E, reaching to a proper distance above the surface ofthe ground, to convey the water into the spout F. That portion of the pump that is above ground is inclosed in the curb Gr, which has no opening except the spout which is attached thereto. At the bottom of the spout a diaphragm, II, stretches across the curb G, the tube E opening into the chamber H above the diaphragm.

Ihe piston is shown at I. Thisis constructed in the usual form and lits accurately the .interior ofthe cylinder A. The piston-rod J is bifurcated at the point of its attachment to the piston, for the purpose of giving space for the play of the piston-valve K. Upon the'upper side of the piston, and in its center, we place the valve K,whieh opens upward, asindicated by the dotted lines in Fig. 2. When the piston is caused to rise, this valve is closed by the pressure of the Water above it, and the piston lifts all of the Water that is in the cylinder, carrying it up the tube E and discharging it above the diaphragm into the spout F.

The upper end of the piston-rod J is provided with a rack, L, which works in a guide, M. This guide M stretches across the chamber Hf, just above the spout F. The rack L, and with it the piston J, is worked up and down by means of the pinion N, which is situated upon the middle of the crank-shaft O. A single revolution of this pinion will move the piston through its whole stroke.

Instead of placing the diaphragm H just below the spout F, it may be placed at any point in the tube E, as shown at H2, and a goose-neck pipe carried from any point below the diaphragm and above the piston, and discharging through or outside ot' the curb G, as indicated by the dotted lines in the drawings. In any case where the diaphragm is placed above the depth of freezing in the winter a vent-hole should be provided to draw the water down below that point when the pump is not in use. Then the'diaphragm is placed inthe pipe E, it should be in the form of a stufiing-box, which will thus serve the double purpose of stopping the `l'low of water upward above that point,but also serves to give steadiness to the ro'd J.

What we claim as our improvement, and desire to secure by Letters Patent, is-

The chamber C, cylinderl A, piston I, pipe E, curb Gr, rack and pinion L N, and diaphragm H, the several parts being constructed, arranged,and operating as and for the purpose set forth.
